A macrobiotic iet (or macrobiotics), from the Greek "macro" (large, long) and "bios" (life), is a dietary regimen that involves eating grains as a staple food supplemented with other foodstuffs such as vegetables and beans, and avoiding the use of highly processed or refined foods. Macrobiotics also address the manner of eating, by recommending against overeating, and requiring that food be chewed thoroughly before swallowing.
